"5G NR will make the best use of a wide range of spectrum bands, and utilizing spectrum bands below 6 GHz is critical for achieving ubiquitous coverage and capacity to address the large number of envisioned 5G use cases. Qualcomm Technologies’ sub-6 GHz 5G NR prototype, which was announced and first showcased in June 2016, consists of both base stations and user equipment (UE) and serves as a testbed for verifying 5G NR capabilities in bands below 6 GHz."

Qualcomm first showed their sub-6 Ghz prototype this past summer, and it will be on display this week at MWC. The company states that the system is designed to demonstrate how 5G NR "can be utilized to efficiently achieve multi-gigabit-per-second data rates at significantly lower latency than today’s 4G LTE networks". New Radio, or NR, is a complex topic as it related to a new OFDM-based wireless standard. OFDM refers to "a digital multi-carrier modulation method" in which "a large number of closely spaced orthogonal sub-carrier signals are used to carry data on several parallel data streams or channels". With 3GPP adopting this standard going forward the "NR" name could stick, just as "LTE" (Long Term Evolution) caught on to describe the 4G wireless standard.

Along with this 5G NR news comes the annoucement of the expansion of its X50 modem family, first announced in October, "to include 5G New Radio (NR) multi-mode chipset solutions compliant with the 3GPP-based 5G NR global system", according to Qualcomm. This 'multi-mode' solution provides full 4G/5G compatibility with "2G/3G/4G/5G functionality in a single chip", with the first commercial devices expected in 2019.

"The new members of the Snapdragon X50 5G modem family are designed to support multi-mode 2G/3G/4G/5G functionality in a single chip, providing simultaneous connectivity across both 4G and 5G networks for robust mobility performance. The single chip solution also supports integrated Gigabit LTE capability, which has been pioneered by Qualcomm Technologies, and is an essential pillar for the 5G mobile experience as the high-speed coverage layer that co-exists and interworks with nascent 5G networks. This set of advanced multimode capabilities is designed to provide seamless Gigabit connectivity – a key requirement for next generation, premium smartphones and mobile computing devices."
